Abeer Mohammed Ali Al-garawyi, Amal Jameel Kadhim, Majid Mohammed Mahmood, pages 537-542
Read Abstract
Methods: In January–April 2022, 45 soil samples were randomly collected from southern Iraq to isolation and identification of keratinophilic fungi, the hair bait method and molecular techniques were used also, detection of mycotoxin achieved by TLC technique then experimental injection in vivo.
Results: The findings showed that 12 (66.7%) out of 18 soil samples that tested positive for the genus Aphanoascus belonged to the species A. terreus. When these isolates were compared to NCBI using PCR sequencing, they were 99% matched. In addition, all these isolates show the capacity to create a range of unidentified secondary metabolites with a variety of colors and flow rates. Only one compound was studied that appeared with a turquoise hue, so we named it A. terreus T (ATT), which has an Rf. of 18.7 cm. The analysis of secondary metabolites with the aid of FTIR and GC-MS chemical tests indicated possibilities; the most probable is that the ATT is an acidic compound. Visual examinations of the skin of rats injected with ATT showed no obvious abnormalities. Microscopically, they appeared normal as well, but with mild inflammatory signs around the hair follicles.
Conclusion: The outcomes represent the first international registration ever made in accordance with what is known about the production of a mycotoxin from A. terreus. This finding is considered the first reference regarding mycotoxin production from A. terreus.

Mohammad Zubair Alam, Absarul Haque, pages 543-548
Read Abstract
Methods: This study screened a library of natural compounds from the ZINC database against the CTX-M-15 protein using the PyRx 0.8 tool. The SwissADME web platform was used to predict the ADMET properties of the five most promising compounds.
Result: The identified hits compounds, ZINC1857626342, ZINC403692, ZINC408773, ZINC57926, and ZINC790938591 exhibited strong binding with CTX-M-15. These compounds interacted with crucial catalytic site residues in the CTX-M-15 protein, particularly Ser70 and Ser130. Notably, the binding energies of these compounds were higher than those of the reference compound avibactam. Furthermore, they exhibited pharmacologically favorable characteristics.
Conclusion: These compounds show promise as potential CTX-M-15 inhibitors to combat bacterial resistance. However, more experimental research is needed to optimize these compounds for their role as CTX-M-15 inhibitors.

Edgar Kafarov, Imran Avduev, Zelimkhan Lechiev, pages 549-554
Read Abstract
Methods: 116 corrosive preparations of the arterial system of the human kidney served as the material for the study. The authors identified their extra-organ branches: a) the number of arterial vessels in the kidney hilum; b) the topographic and anatomical features of the renal artery trunks. In a 3D projection, zones of local zonal blood supply to areas of the renal parenchyma were identified, depending on the di- and trichotomic variants of the division of the main renal artery, A. renalis (I).
Results: It was found that some lines of the passage of the zones of natural divisibility of the kidneys with different variants of the division of A. renalis (I). There were from 5 to 7 (6 ± 1) segments in the kidneys on average. It is possible that if a four-zone blood supply system with corresponding zones of natural kidney divisibility is found in the kidneys, where the zones mostly don’t coincide with the boundaries of the passage of segments in their classical version, the number of segments will be even greater.
Conclusion: The results of the conducted study show that considering the generally accepted zones and boundaries of the passage of segments with zones of natural divisibility, which were not previously considered, the kidneys have an individual segmental structure, which requires revision. The authors believe that the generally accepted classical five-segment kidney model is outdated.

Molecular identification of Epstein-Barr virus in human placental tissue
Methods: The genomic sequences connected to the latent EBV gene and the levels of lytic EBV gene expression in placental chorionic villous cells are examined in this work. A total of 86 placentas from patients who had miscarriage and 54 placentas from individuals who had successful births were obtained for analysis.
Results: The research employed QPCR to detect the BRLF1 (Rta) EBV lytic gene and quantify DNA burden in miscarriage patients and controls. In miscarriage patients, endpoint PCR and Sanger sequencing validated a particular region of the EBER1 EBV latent gene. BRLF1 gene presence ranged from 2.5 × 102 to 9.3 × 104 copies/mL in 75 miscarriage patients. However, a sample of 5 people with healthy deliveries showed a range of 2.0 × 102 to 2.9 × 102 copies/mL. All miscarriage samples were observed EBER1. The sequencing results indicated full sequence identity to EBV strains.
Conclusion: The detection of EBV gene expression in placental tissues in Iraq is a novel finding. The examination of EBV is of utmost importance in pregnant women who are experiencing severe illness, since it has the potential to lead to mortality in both the mother and the developing fetus.

Plausible inhibitors of malaria parasite Plasmodium falciparum 3D7 ATP-dependent DNA helicase
Mohammad Othman Alkurbi, pages 644-650
Methods: The bark of C. verum procured from the market was subjected to hydro-distillation procedure for extraction of the essential oil. The extracted essential oil was subjected to in-vitro evaluation in terms of percent sporulation and oocysts damage at six different concentrations (0.31, 0.625, 1.25, 2.5, 5 and 10% v/v). Similarly, for the in-vivo trial, 72 broiler chicks were randomly divided into six equal groups (A, B, C, D, E and F). The first five groups were infected with oocysts of mixed Eimeria species while the sixth group was kept as non-infected. When the chicks were 14 days old, the infected groups were orally given 55000 oocysts per bird. On the same day 14, the groups A, B and C were given C. verum essential oil at concentrations of 1, 2 and 3% respectively in feed whereas groups D, E and F served as positive control (Toltrazuril® treated), negative control and the normal control respectively.
Result: The results revealed C. verum oil to have an effect on the percent sporulation and oocysts damage. The oil also improved the FCR, lesion score, oocysts score, fecal score and serum biochemical parameters in the treated broilers. However, it had no significant positive effect on the hematological parameters like Hb, PCV and blood cells count, and the weight of internal organs in broilers. For most of the parameters, C. verum essential oil showed a dose-dependent effect.
Conclusion: In nutshell, C. verum essential oil possesses significant anticoccidial potential as demonstrated by the results of both the in-vitro and the in-vivo experiments. However, further studies are required for its validation and commercialization in the poultry sector.

Green Nano-synthesis: Salix alba Bark-Derived Zinc Oxide Nanoparticle and their nematicidal Efficacy against root knot nematode Meloidogyne incognita
Methods: Phytochemical analyses of Salix alba bark extract were conducted, and nanoparticles of the same extract were synthesized and characterized using UV-vis spectroscopy, XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy) and EDX (Energy Dispersive X-ray Spectroscopy) techniques.
Results: The qualitative phytochemical analysis of Salix alba bark extract revealed the presence of phenolics, flavonoids, reducing sugars, and saponins. When applied on juveniles of the plant parasitic nematode Meloidogyne incognita, the nanoparticles demonstrated a dose and time-dependent impact. After 24 hours, the highest concentration (1000 µg/ml) of nanoparticles exhibited the greatest mortality, reaching 82.2%, while the lowest concentration resulted in a mortality rate of 34.5%. Similarly, at the 48-hour mark, the highest mortality (92.2%) was observed with 1000 µg/ml of nanoparticles, whereas the lowest concentration yielded a mortality rate of 54.5%. Extending the observation period to 72 hours, the mortality rate peaked at 98.33% with the highest nanoparticle concentration (1000 µg/ml), and the lowest mortality rate was recorded at the lowest dose, amounting to 72.5%. These results underscore the dose and time-dependent efficacy of Salix alba bark-derived nanoparticles against Meloidogyne incognita.
Conclusion: Our findings suggest that zinc oxide nanoparticles synthesized from Salix alba bark can be an effective agent against plant parasitic nematode Meloidogyne incognita. Further experiments are recommended to study the impact of these nanoparticles on other biotic stresses.
